00:46 A potato pangenome

Researchers have created a ‘pangenome’ containing the genomes of multiple potato types, something they believe can help make it easier to breed and sequence new varieties. The potato’s complicated genetics has made it difficult to sequence the plant’s genome, but improvements in technology have allowed the team to combine sequences, allowing then to look for subtle differences in between varieties.
